SPECIFICATION forming part of Letters Patent NO. 599,639, dated February22, 1898.

Application filed April 8, 1897. Serial No. 631,264. (No model.)

useful improvements in metallic rail-support! ing girders or cross-tiesforrailroads, and has for its object to provide a simplifiedconstruction of tie of this class andnovel means for attaching the railthereto.

To the accomplishment of this end my invention consists in certain noveldetails of construction, combinations, and arran gement of parts, aswill be hereinafter more fully described, and specifically set forth inthe appended claim.

In the accompanying drawings, Figure 1 is a side elevation of a tieembodying my invention. Fig. 2 is a vertical longitudinal section of thesame. Fig. 3 is a side elevation view of the tie with parts removed;Fig. 4, a plan view of the clamping-plates; Fig. 5, a plan view of thenut-lock plate, and Fig. 6 a detail of the center bolt and pin whichsecures the nut-lock plate.

Like numerals of reference designate correspending parts throughout theseveral figures of the drawings.

Referring to the drawings, the numeral 1 designates the metallicrailroad-tie,which consists of an ordinary box-casting. This tie isformed on its upper side with a recess 2, provided at each end thereofwith `a groove 3 of a width equal to one-half of the width of the baseofthe rail et. The edges of the recessed portion adjoining the saidgrooves are beveled or inclined, as shown at 5, in order to correspondto the conguration of the upper side of the lbase-flange 6 of said rail.Two

metallic retaining-plates 7 8 are positioned in the said recess of therail-tie and have their square ends abutting, as shown at 9. Theopposite ends of said retaining-plates are formed with base-grooves 1011, adapted to `the said grooves are beveled or inclined like the edgesv5 of the rail-tie to conform to the configuration of the upper surfaceof the baseflange of the rail, and thereby securely hold the rail inposition. These retaining-plates are held by two bolts 13 14, havingtheir heads placed on the under side of the tie and their shaftsprojecting through vertical openings 15 therein, and nuts 16 engagingthe projecting threaded ends of said bolts. A nut-lock plate 17 isprovided to engage the said nuts 16 and prevent the same from turningand becoming disengaged. This plate extends across the point of junctionofthe two retaining-plates 7 8 and is provided in the end thereof withan open rectangular slot 18, which incloses the said nuts and preventsthe same from turning, as will be readily understood. The nut-lock plateis retained in position by a bolt 19, projecting from the upper sidedown through the tie and having its shank 19a formed with a verticalslot 20, having serrated edges 21. A locking-pin 22 is formed with ahead 22a and passes through the said slot and is then bent at an angle,as shown, to prevent disconnection, the serrated edges also assisting inpreventing movement of said pin.

My invention provides a simple and efficient construction of rail-tieand rail-attaching mechanism therefor, by means of which the rails maybe readily secured thereto and removed therefrom when substituting newrails, and the employment of spikes for securing the rails is dispensedwith.

Having thus described the invention,what is claimed as new, and desiredto be secured by Letters Patent, is-

In a rail-tie, the combination of the tie provided with a centrallongitudinal recess and a groove at each end thereof adapted to receivethe base-flange of the rail, two retainingplates seated -in said recesstheir inner ends contacting and provided at their outer ends withgrooves acting in conjunction with the grooves of the tie to clamp thebase-flange of the rail, bolts passed upward from the un- IOO 1o one ofthe retaining-plates and the lockingplate and securing all of said partstogether, substantially as described.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
